GWT. Set url without submit

Question

Can i change url(set parameter) without submit? I found this method http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/user/client/Window.Location.html#

Why are you trying to do this? Generally speaking, GWT apps don't change pages - thus they are normally SPAs (single page applications)

When you load a new page from a server, you will lose the state on that page. You can change the hash part of the URL as that won't return to the server, like this:

String newURL = Window.Location.createUrlBuilder().setHash("newhash").buildString();
Window.Location.replace(newURL);

However, if you're going to do this, I would recommend taking a look at GWT's MVP framework, which has built in support for managing locations using hash tokens.
